Add 'name' as the passed in filepath for test_line_insert_ensure_before_first_line test
Add 'name' as the passed in filepath for test_line_insert_ensure_before_first_line test

With 'foo', the test fails with an unknown file KeyError - we need to use the "name"
variable instead.

Fixes the test_line_insert_ensure_before_first_line test.
